Malaysia is an ex‐colonial, newly‐industrialising country, with a sustained high economic growth rate averaging eight per cent GDP per annum over the past ten years. Within such a rapidly booming economy, the pace of social, economic and political change is fast, as is the pace of technological change. Other things being equal, these are the changes in which environmental hazards can be magnified. As a result of rapid economic development, physical systems are disturbed and changed. For example, the modification of the hydrological cycle due to deforestation, urbanisation, development of hill slopes and other human land use have given rise to increased risks of landslides. In recent years, the collapse of a block of luxury condominiums in Kuala Lumpur, the Genting Highland and Pos Dipang landslide tragedies as well as other landslide disasters have caused substantial loss of life and damage to property and infrastructure. Combined with intensive development of hill slopes and hill land for housing, recreation, tourism, agriculture, highway and dam construction, and other human induced land use changes, the exposure and vulnerability of human populations to landslide hazards have also increased. Other reasons, largely structural, such as persistent poverty, low residential and occupational mobility, and landlessness, manifested in illegal squatting and farming on hill slopes and foothills have also contributed to increased vulnerability of large communities to landslide hazards in many parts of the country. As Malaysia pushes ahead to meet its target of becoming a fully industrialised country by the year 2020, further environmental degradation is expected to occur. Notwithstanding other aspects of environmental degradation, the occurrence of landslide hazards is expected to become a common feature of Malaysian life.

Increasingly, land is a scarce resource which is much sought after in Penang Island, Malaysia. This is because Penang is largely made up of steep topography and much of the lowland areas are already developed. Penang is one of the many rapidly industrialising states in Malaysia with a largely urban populace. In recent decades, efforts at industrialisation and the development of other economic sectors have been intensified, leading to greater urbanisation and greater pressures on land. Although land reclamation has eased the pressures somewhat, it is not enough to satisfy the high demand for land on the island. As such, developers have turned to the remaining hill land on the island. Many hills and their environs are already being developed and many hill projects are in the pipe line. This has led to many environmental problems such as deforestation, decimation of water catchments, destruction of endangered fauna and flora, soil erosion, landslides, water pollution, sedimentation and downstream flooding. Some of these problems have been exacerbated and turned into disasters due to the extremely fragile and sensitive nature of hill ecosystems. Despite such problems, the State Government has decided to lift the freeze on development of hill land since January 1998, and this has effectively opened up all hill land for development on the island. Therefore, hill land needs to be protected and conserved by other means and this study recommends the adoption of a policy of “No development in all ecologically and environmentally sensitive areas”, the setting up of a Hill Land Technical Committee (HLTC) to manage all developments pertaining to hill land and to gazette all hill land in the State, and the use of state‐of‐the‐art remote sensing and Geographic Information System (GIS) technology to monitor and control development activities on hill land in Penang.

The purpose of this paper is to attempt to generate a better, systematic and scientific understanding of the basic reasons behind slope instability to help in developing the basic principles of landslide hazard zonation, monitoring and forecasting of landslide hazards for better and more effective landslide hazard mitigation and management.

The study is based on extensive field observations and intensive reviews of literature from secondary sources.

Mass movements especially landslides as they are known to common man are a recurring natural phenomenon and are an integral part of any geological/geomorphological circle of landform development through sequential development of slopes in any elevated region and especially in young fold mountain chains.

The paper presents a valuable insight into the basic reasons behind a landslide to spread awareness, to educate and sensitize people towards better and effective landslide hazard mitigation and thereby ensure people's participation in disaster management. It also aims to initiate and encourage research in the field of landslide management.

Landslides occur frequently and without any appreciable warning as such causing havoc and often insurmountable damage to life and property but despite their uncertainty, their causative factors and indicators of slope instability are very well known to an extent that the magnitude of these events, susceptible areas, the timing of such events and their potential impact can be studied, analyzed and evaluated on the basis of past occurrences and existing knowledge to mitigate their impact. The real value of the present study is to minimize losses due to landslides through better knowledge and enhanced levels of understanding of the phenomenon and its management by simply avoiding those particular reasons that could lead to slope instability problems.

The overall objective of this study is envisaged to provide decision makers with actionable insights and access to multi-risk maps for the most in-danger stave churches (SCs) among the existing 28 churches at high spatial resolution to better understand, reduce and mitigate single- and multi-risk. In addition, the present contribution aims to provide decision makers with some information to face the exacerbation of the risk caused by the expected climate change.

Material and data collection started with the consultation of the available literature related to: (1) SCs' conservation status, (2) available methodologies suitable in multi-hazard approach and (3) vulnerability leading indicators to consider when dealing with the impact of natural hazards specifically on immovable cultural heritage.

The paper contributes to a better understanding of place-based vulnerability with local mapping dimension also considering future threats posed by climate change. The results highlight the danger at which the SCs of Røldal, in case of floods, and of Ringebu, Torpo and Øye, in case of landslide, may face and stress the urgency of increasing awareness and preparedness on these potential hazards.

The contribution for the first time aims to homogeneously collect and report all together existing spread information on architectural features, conservation status and geographical attributes for the whole group of SCs by accompanying this information with as much as possible complete 2D sections collection from existing drawings and novel 3D drawn sketches created for this contribution. Then the paper contributes to a better understanding of place-based vulnerability with local mapping dimension also considering future threats posed by climate change. Then it highlights the danger of floods and landslides at which the 28 SCs are subjected. Finally it reports how these risks will change under the ongoing impact of climate change.

The purpose of this paper is to assess the land utilization in the erosion and landslide vulnerable mountainous region using the Rapid Appraisal for Agricultural Land Utilization (RApALU) model.

A multidimensional RApALU model is used for sustainable agriculture land utilization.

Ecological dimension was less sustainable, whereas socio-economic, socio-cultural, and eco-technological dimensions were comparatively more sustainable. It was found from the analysis that 9 out of 21 attributes have sensitive effect on the sustainability index and status.

One of the implications of this research is that this model could be used to quickly measure the arrangement of an area that is experiencing environmental problems so that the land use planning process could be done more effectively and efficiently. The parameters used in each variable could be chosen by the researchers themselves according to location. As far as known by the researcher, the methods used have not been well integrated, they are still separated, for example, only physical problems, and social problems have not been measured properly. This model is not perfect yet, and it could be developed further because environmental problems are very complex and could be different from one location to another.

RApALU analysis can be used as preliminary analysis to comprehend general and overall description on the status of the sustainability index of land utilization for agriculture in hilly mountainous regions. The study confirmed that RApALU analysis can help determine the status of the sustainability of land utilization in intricate areas. This technique was able to comprehensively identify important factors affecting sustainability status of various dimensions.

The aim of this paper is to present a discussion on prognosis and mitigation of major landslide zones in an attempt to minimize the impact of such disasters in future. A case study on the sequence of sliding events of Varunavat Parvat, Uttarkashi (India), response of masses and administration and causative factors of sliding events has been presented in detail for prognosis and mitigation of large slide zones.

The prognosis and mitigation strategy discussed is based on the monitoring of mass wasting zones through field investigations and satellite image analysis (of pre‐ and post‐landslide period images) and experiential learning and interaction with village elders in landslide hazard‐prone Himalayan terrain.

The paper finds that Himalayan habitations such as Uttarkashi (which is situated in an area of fragile rocks, complex tectonics, seismic activity and cloud burst‐prone unstable hill slopes with colluvium and old slide zones) should have minimum anthropogenic activity in the form of slope cutting for road or building construction.

The paper reflects the author's individual understanding of causative factors and indications of landslides in Varunavat Parvat area in Uttarkashi township of Uttarakhand (India).

The paper calls for amalgamation of experience‐based local knowledge of villagers of landslide‐prone areas and modern scientific and technical know‐how and above all the coordinated efforts of community and authorities for prognosis and mitigation of large‐scale landslides in the inhabited areas. It has been further emphasized that sensitization and awareness programs and strict implementation of land‐use regulations are vital components of effective mitigation strategy.

The purpose of the paper is to evaluate the published information on natural hazards and their implications in the environment.

The published data/information on natural hazards were collected and analyzed.

An analysis of the disaster data (1983‐2003) showed that a total of 1,063 lives on an average were claimed by natural calamities (earthquake, landslide, flood, fire, windstorm, epidemics and avalanche) each year. Water‐induced (flood and landslide) disasters alone contributed to 31.8 percent of the total deaths. Epidemics claimed the maximum number of deaths (55.9 percent) especially in the post‐disaster period. Many of these epidemics occurred due to the contamination of the drinking water sources by flash floods, and landslides. Poor sanitation, unsafe water and unhealthy living conditions contributed to major outbreaks of water‐borne diseases especially in the monsoon period claiming numerous lives.

Published information on natural hazards and implications on environment is limited. This paper integrated and analyzed 21 years of disaster data. A discussion of environmental implication is provided.

The purpose of the study is to assess the environmental and socio‐economic impacts and risks of climate change through GIS database management system (DBMS) on land use‐informatics and climate‐informatics. The Dabka watershed constitutes a part of the Kosi Basin in the Lesser Himalaya, India in district Nainital has been selected for the case illustration.

Land use‐informatics consists of land use mapping and change diction, i.e. decadal changes and annual changes. Climate‐informatics consists of climate change detection through daily, monthly and annual weather data for a period of 25 years.

The exercise revealed that oak and pine forests have decreased, respectively, by 25 percent (4.48 km²) and 3 percent (0.28 km²) thus bringing a decline of 4.76 km² forest in the watershed during 1990 to 2010. But, due to climate change the mixed forest taking place of oak forest in certain pockets and consequently the mixed forest in the catchment increased by 18 percent (2.3 km²) during the same period which reduced the overall loss of forests in the region but its not eco‐friendly as the oak forest. Barren land increased 1.21 km² (56 percent), riverbed increased 0.78 km² (52 percent) and cultivated land increased about 0.63 km² (3 percent) during the period of 1990 to 2010. Out of the total seven classes of the land use land cover, five classes (i.e. Oak, Pine, Mixed, Barren and Riverbed) are being changed dominantly due to climate change factor and anthropogenic factors plays a supporting role whereas only two classes (scrub land and agricultural land) are being changed dominantly by anthropogenic factors and climate change factors plays a supporting role. Expansion of mixed forest land brought out due to upslope shifting of existing forest species due to climate change factor only because upslope areas getting warmer than past with the rate of 9°C‐12°C/two decades. Consequently, the results concluded that the high rate of land use change accelerating several environmental problems such as high runoff, flash flood, river‐line flood and soil erosion during monsoon season and drought during non‐monsoon period. These environmental problems cause great loss to life and property and poses serious threat to the process of development with have far‐reaching economic and social consequences.

This study generated primary data on land use‐informatics and climate‐informatics to integrate each‐other for impact assessment and mitigation through sustainable land use as constitutes a part of a multidisciplinary project, Department of Science and Technology (D.S.T.) Government of India.

Floods and landslide threats were addressed under the Frontline process in the city of Limbe, Southwestern Cameroon. The purpose of this paper is to present actions undertaken through building local community resilience to floods which are a major threat in the city, with impacts on the local community ranging from death to complete destruction of services and livelihoods.

The actions carried out were informed by the GNDR-supported Frontline survey conducted in 2015 in which the Lower Motowoh community rated floods as an important threat. A series of reflection and learning sessions with the community members was carried out to better understand the problem. Scoping studies on the causes and extent of floods along river Njengele were undertaken by GEADIRR and the community team.

The findings of this paper indicated that the main problem resulted from river channel blockage caused by indiscriminate dumping of refuse into the waterway and sediment deposition from upstream. Further reflection and action planning led to preparatory meetings between GEADIRR and ten community leaders. The unanimous action adopted was to dredge the river. Dredging was carried out in late April and early May of 2016 using a hired bulldozer.

Follow-up shows that after many years of misery from floods, often associated with the loss of loved ones and property, about 500 community residents who benefited from the action did not go through this dreadful ordeal again during the rains of 2016 and 2017. People are currently rebuilding on the reclaimed land which was previously abandoned due to flooding.

Current challenges include changing the mindset of community members about the adverse effects of indiscriminate dumping of household waste into the waterway. It was also a big challenge convincing some members of the community who felt that floods are a natural phenomenon unstoppable by man.
